Charger inop

Looks like maybe they were using it at a campground with 30 amp service.

What " JohnnieB " said about dangerous is an understatement! What kind of show do you think you would see if the dryer plug was plugged in to a dryer outlet? A kid wouldn't know any better!

JohnnieB,You are correct the dryer plug is the plug that goes to the cart and there is a matching recipical on the cart for the plug. We check the diodes,capactor and the fuse,both check good. We unbolted the transformer it has gotten extremely hot on the bottom.When you check the output from the transformer it reads 5v. Seems to me the transformer is shot? The charger at Sams is 36v-12a,seems alot smaller charger than what the cart uses,36v-25a. What do you think?

1. Your right, 5V isn't a good sign whether it's AC or DC.
To check the transformer (and capacitor), you've got to completely unload it and from what I see in the picture you posted, you'll have to unsolder the transformer leads attached to the diodes to do that. The capacitor has push-on connectors, so it is easy to disconnect, but be careful, it can have about 660V on it.

With the leads of an AC voltmeter across the lead that were disconnected from the diodes, you should get about 80 VAC with capacitor disconnected.
If not, the transformer is bad.

I you do, reconnect the capacitor.
With the capacitor connected, you should get about 100 VAC.
If not, the capacitor is bad.

The transformer you've got is a true center-tap rather than two separate windings tied together to form a single center-tapped one like was done in later chargers, so the voltages given above may be off by a ways, but the voltage with the capacitor connected ought to be significantly more than without it connected.

Note: While the transformer is disconnected from the diodes, you have an opportunity to check them with an Ohmmeter individually rather than in parallel as they are when they're connected to transformer.

2. Two schools of thought on this. Some people think batteries ought to be charged fast, other think they ought to be charged slow. Personally, I don't think the difference between a 12A charge rate and a 25A charge rate matters much, other than it take twice as long to charge the batteries.

Here is a thread on the Stanley charger and there may be others.
